Scrolling is certainly special at least in some way:
- Implementation-wise, not all commands simulate redisplay during their
operation. Given that the heavy lifting has probably already been done,
maybe skipping redisplay doesn't help save a lot of work anyway? At
least without extra tricks like jit-lock-defer-time which speed up both
simulated and "real" redisplay, making skipping redisplay less essential
anyway.
- As we talked about "precision", the user needs to see the buffer
contents to see where they are scrolling to, and where to stop. If the
number of screens you need to scroll is >1, you can likely never decide
on the necessary number of scrolls in advance. This is not the case for
many other Emacs commands. E.g., if I use find-file, I usually don't
need to see the prompt, and I can start typing the desired file name in
advance.

In a way, the comment supports my point:
...all the hard work of jit-locking is "wasted"...
The current approach helps avoid this most of the time, but it errs on
the side of skipping. I suggest it might be better to err on the side of
not skipping, for a certain set of commands at least.
